Referring to the drawings'wherein like referthe several views, Figs. 1 to 5, inclusive, illustrate ya portable iiuid massage `apparatus or appliance `embodying the presentinvention andincluding a iiexible conduit and a similar conduit 6 enclosed in the conduit 5 and providedwith ribs 7 that khold the conduit 5 in spaced relation with theconduit 6 and form therewith `channels 8 extending between and longitudinally of Vsaid conduits. The

conduit 5 has one end connected, in any suitable manner, with one extremity of a sleeve 9 which is or greaterdiameter than the conduit 6, as clearly shown in Fig. 3 of the drawings. The conduit 6 extends into the sleeve 9 in spaced relation therewith, and said conduit has one end thereof engaged by a reduced portion 10 formedon said sleeve at the endlthereof opposite that connected with the conduit 5. The conduit 6 has fitted therein adjacent the reduced portion 10 of sleeve 9, the reduced tubular extension 11 of a coupling sleeve 12 provided interiorly thereof with a rubber coupling 13 between which and thev coupling sleeve 12 is arranged a screen 14. The extension 11 the adjacent end of the conduit 6, and the reduced sleeve portion 10 may, if desired, be se- `ence characters designate like parts throughout CII b34 such as indicated in the drawings.

curely clamped together, bya suitable clamp engaged thereover.

The sleeve 9 has secured to or formed integrally therewith, a tubular extension 15, and secured, in any suitable manner, to said extension is one extremity ofa exible conduit 17. The opposite extremity of the conduit 17 is secured, in any suitable manner, on one end of a U-shaped tubular support 18 provided in its opposite end with a screen 19.

The end of the conduit 6 opposite that connected with the coupling sleeve 12 is connected, in any suitable manner, with one extremity of a conduit 20. rIhis conduit 20 extends longitudinally and concentrically througha conduit 21 and forms therewith a manifold, indicated broadly at 22. The end of the conduit 5 opposite that connected with the sleeve 9, is secured in any suitable manner on the end of the conduit 21 adjacent the connection for the conduit 6 with the conduit 20.

Mounted on the conduit 20, and secured thereto Ain any suitable manner, is a washer 23 provided in the periphery thereof with a series of openings 24. This washer 23 is tted in one end of the conduit 21 and secured thereto in any suitable manner, and the openings 24 in said washer establish communication between the channels 8 and the interior of the conduit 21. The conduit 20 has fitted in the end thereof opposite that secured 'to the washer 23, a plug 25 which is secured to said conduit in any suitable manner.

The plug 25 is secured to or formed integrally with a cap 26 that is fitted in the adjacent end of the conduit 21 and secured thereto in any suitable manner. The manifold 22 extends within a guard or casing 27 secured in any suitable manner to the conduit 2l., and mounted on said conduit beferent diameters and lengths respectively, the

tubes 32 vpressed ts in suitable openings formed in the conduit 20 and the tubes 33 having i pressed fits in suitable openings formed in the yconduit 21. The injectors 29 serve tomix liquid and gas received from the conduits 20 and 21, re-

spectively, and discharge jets or sprays of said mixture under pressure and at high velocity through the openings 30 in the guard or casing 27 for application to the body of a person as hereinafter pointed out.

The above described portable fluid massage apparatus or appliance may be used in tubs, pools, or other bathing places as, for example, in a tub This tub `34 is equipped with a mixing faucet 35 for hot and "cold water received from any suitable source ythrough pipes such as indicated at 36, and said and water under pressure is delivered through conduit 6 into the conduit 20 of manifold 22. The conduit 17, in the use of the portable apparatus or appliance as stated, is preferably sup- A ported fromthe upper edge of the tub 34 by the 'eU-shaped support 18 whichis engaged thereover.

The water delivered under pressure into the conduit 20, passes through the tubes 32 and 33 of injectors 29 and is discharged therefrom through the openings 3G of guard or casing 31 into the liquid in the tub or pool 34, for application to the body of a person therein. The water thus delivered into the injectors ,29 and discharged 'therefrom as stated, creates suction in the member 18, conduit 17, channels 8 between sleeve 9, conduit 6, and conduit 5, and also in the conduit 21 and the nozzle 33 communicating therewith. Air is thus drawn into the nozzle 33 through the described connections therefor with the me .aber 13, said air being entrained and mixed in said nozzie with e water delivered therein, and the mixture being discharged from the injectors into the liquid in the tub or pool 34 for application to the bod-y of a person therein. The jets or sprays thus delivered from the injectors 29, when applied under water against the body of a person therein, produce `a fluid vibratory massage on the body of the person with resulting invigorating and healthful effects attending the same. At the same time, jets or sprays formed and delivered by the injectors in the liquid in the tub or pool, as described, impart vigorous and thorough agitation to said liquid with an accompanying restful and pleasant eect on the body of the person.

The present invention is also capable of use in other forms of appliances and equipment, and in the embodiment of said invention shown in Figs. 6 to 8, inclusive, of the drawings, a manifold, indicated broadly at 34', is secured to, and below, a perforated support 35' having openings 36 therein with which injectors, indicated broadly at 37', and secured to said manifold, are disposed in axial alinement. The injectors 37 are disposed in spaced relation with the support 35 below the openings 36 therein, and the manifold 34 is secured to the support, as by cross members 38',

39', which are fastened in any suitable manner yto said support and said manifold. The support 35' is provided with legs 40 having cushioned feet 41 resting on the bottom of the tub 34, said legs serving to support the manifold 34 and the support 35 on the bottom of said tub in spaced relation therewith.

The manifold 34' may be connected, as by a flexible conduit 42, with the faucet 35. For this purpose, the conduit 42 is provided at one end thereof with a coupling 43 which may be detachably connected with said faucet. The opposite end of the conduit 42 is connected in any suitable manner with a tubular extension 44 of a manifold header 45 extending transversely of the manifold 34 at one end thereof. This header 45 has connected therewith corresponding ends of manifold pipes or conduits 46 which extend through suitable openings formed in a manifold header 47 secured in any suitable manner to the cross member 38' on the perforated support 35. The opposite ends of the pipes or conduits 46 are closed by plugs 48 secured thereto in any suitable manner and formed on caps 49. The caps 49 are secured, in any suitable manner, in corresponding ends of manifold pipes or conduits 50 through whi .i the pipes or conduits 46 extend longitudinally thereof andy concentrically therewith. Said ends of the pipes or conduits 50 are secured in any suitable manner to the cross member 39 on the perforated support 35', and the opposite ends of the pipes or conduits 50 are secured in any suitable manner to the header 47 in suitable openings therein.

The header 47 has connected therewith, at one end thereof, an air pipe or conduit 51 which extendsvertically to the top of the tub 34 between a side wall of the same and the support 35. The injectors 37 are comprised by inner tubes or nozzles 52 communicating with the pipes or conduits 46 and having pressed lits in suitable openings therein, and outer tubes or nozzles 53 extending over the tubes or nozzles 52 in communication with the pipes or conduits and having pressed iits in suitable openings therein. Water delivered under pressureV from the faucet 35 through conduit 42 into header 45 and conduits 46, is diecharged from the latter through the nozzles 52, 53 and the openings `36 in support 35', into the tub or pool 34 for application to the body of a person on said support. Suction is thus created in the pipe 51, header 47, conduits 50, and nozzles 53, so that air from the atmosphere is drawn into said nozzles through the' described connections therefor with the pipe 5l. Air is thus entrained and mixed with the water in the nozzles 53, and the mixture is discharged from the injectors 37', through the openings 36' in support 35", in jets or sprays which, when applied to the body of a person under water in the tub or pool 34 and positioned on said support, produce an invigorating and healthful massage, with an accompanying vigorous and thorough agitation of the water in the tub or pool and a resulting restful and pleasant effect upon the body of the person.

In the embodiment of the invention shown in Figs. 9 to il, inclusive, of the drawings, the manifold and injectors, indicated broadly at 54 and 55, respectively, are supplied with air or other gas under pressure, instead of water or other liquid under pressure. The air or other gas under pressure may be derived from any suitable source, herein shown as a rotary compressor 56 adapted to deliver air under pressure tothe manifold 54 and the injectors 55. The air inlet for the rotary compressor 56 is indicated at 57, and the driven shaft 58 of said compressor has fixed thereon a sprocket 59 around which passes a chain 60. The chain 60 also passes arounda sprocket 6l which is xed on the armature shaft 62 of an electric motor 63 which receives current from any suitable source and is controlled by any suitable type of switch (not shown). Air under pressure is delivered by the compressor from the outlet 64 thereof through a pipe 65 having one end connected with said outlet. The opposite end of the pipe 65 is connected in any suitable manner with a tubular extension 66v of a manifold header 67 extending transversely of the'rnanifold 54 at one end thereof. The manifold 54, in turn, is connected with, and supported below, a support 35' such as included in the previously described embodiments of the invention, saidl support resting on the bottom of the tub 34 to hold the manifold in spaced relation therewith, and the injectors 55 being disposed below the support 35 in alinernent with the openings 36' therein.

The header 67 has connected therewith corresponding ends of manifold pipes or conduits 68 extending in suitable openings in said header and secured thereto in any suitable manner. The opposite ends of the pipes or conduits 68 are closed by plugs 69 secured in any suitable manner to said conduits and formed on caps 70 provided peripherally '..iereof with series of openings 7l. The caps 76 are fitted in corresponding ends of manifoldpipes or conduits 72 and secured thereto in any suitable manner, and said pipes or conduits have extending therethrough, in spaced concentric relation therewith, the pipes or con-- duits 68, as clearly shown in Figs. l0 and 11 of the drawings. The opposite ends of thepipes `or conduitstlz have fitted: therein, andse'cured theretoin any `suitable. manner, washers or plugs 73 which, if desired, may be provided` perpherally theref with: openings.v 73. The pipes or conduits 68 extend through suitable openings in the washers or plugs 73 and the latter are secured in any suitable manner to said pipes or conduits.

The injectors 55 comprise inner tubes or nozzlesf74 communicatingr with the pipes or conduits 68 and having pressed fit in suitable openings therein, and outer tubes or nozzles 75 extending over and above the inner tubes or nozzlesl 74' in communication with the outer pipes or conduits into said pipes or conduits and the outer tubesl or nozzles 75, mixed therein with the air or gas under pressure, and discharged therewith asa mixture from the injectors through the openings 36 in support 35' for application to the body of a person positioned on said support in the liquid in the tub or pool. The high velocity jets or sprays thus formed and applied to the body of the. person, produce an invigorating and healthful fluid massage on the body of the person, which is accompanied by a vigorous and thorough agitation of the liquidin the tub or pool imparted thereto by said jets or sprays and causing a pleasant and restful effect on the body of the person receiving the fluid massage, kas aforesaid.

In the embodiment of the invention shown in Fig. 12 of the drawings, the manifold, injectors, perforated support, and mounting of the same', are the same as illustrated and described in connection with the embodiment of the invention shown in Figs. 6 to 8, inclusive, of the drawings. In the embodiment of the invention shown in Fig. 12 of the drawings, however,v the water is circulated continuously in a closed circuit including the manifold 34'. Accordingly, the water or other liquid in the tub or pool 34 is withdrawn therefrom through a stand pipe 76 mounted on the support 35' over a suitable opening therein and .connected with one end of a pipe or conduit 77 provided with a suitable check valve 78. The opposite end of the pipe or conduit 77 is connected with the' inlet 79 of a rotary pump 80 the driven shaft 8l of which has fixed thereon a sprocket 82. Passing around the sprocket 82 is a chain 83 which also passes around a sprocket 84 that is xed on the armature shaft 85 of an electric motor 86 supplied with current from any suitable source and controlled by any suitable type of switch (not shown) The pump 88 is thus driven through the described driving connections therefor with )1 51.'

the motor 86, and draws water into said pump through the described connections therefor with the stand pipe 76. The water is discharged from the pump 80 through the outlet 87 kthereof and a pipe or conduit 88 having one end connected in any suitable manner with said outlet. The opposite end of the pipe or conduit 88 is connected in any suitable manner with the upper end of a pipe or conduit 89 extending downwardly in the stand pipe 76 through a suitable packing gland 98 in the upper end thereof. The lower end of the pipe or conduit 89 is connected with the extension 44 of the header 45, and it will thus appear, that the water drawn from the `tub 34 is circulated continuously in a closed circuit including the manifold 34' and stand pipe 76, and the described connections therefor with the pump 8G. The construction and operation of the embodiment of the invention shown in Fig. 12 of the drawings, is otherwise the same as the construction and operation of the embodiment of the invention shown in Figs. 6 to 8 of the drawings.

It will appear, from the foregoing, that in all embodiments of the present invention, water or other liquid may be delivered under pressure to the injectors thereof to entrain air or other gas therewith, or the air or other gas may be delivered under pressure to the injectors to entrain the Water or other liquid therewith. It will further appear, that various liquids, gases, and mixtures of the saine may be employed, and that either may have as a constituent thereof, if desired, a medicinal component which may be applied to the body of the person simultaneously '-.vith the fluid massage treatments. It will further appear, that in all embodiments of the present invention, the high velocity jets or sprays delivered into the liquid or water in the tub or pool, will cause a vigorous and thorough agitation of the water and thus create a pleasant and restful effect on the body of the person being treated.
